The PRC crane shall not be boarded without permission of the supervisor in charge of
crane operations in the area.

Using the power ON/OFF switch(es), the person boarding the PRC crane shall switch
the portable remote controller to ‘OFF’ and take it with him or her on to the crane.
When the controller is equipped with a STOP button, this shall be set to the ‘STOP’
position before switching off power to the controller.
+
If the boarding party consists of more than one person, one person shall be designated
as the leader of the boarding party.

The leader shall board the crane first, open and lock out the main switch (securing it
with a padlock), and then signal the other members of the party that it is safe for them
to board the crane.

If it is necessary to have the control circuits on the crane energized, the repair crew
leader shall open all power circuits to the motions before closing the main switch.

crew leader shall insure all tools and materials are stowed or tightly restrained before
the crane is moved.

controller is returned to operational use.
